M27 Continued

I’m not sure what to think of this image. There’s a fair amount of detail, also the outer regions are visible. It’s fake colors anyway so I tried to balance colers for an esthetic appearance combined with a maximum of detail. The thing is, when you look at the individual B/W images, they seem far better in terms of quality, smoothness, noise and detail. It’s when combing them into color that they suddenly require maximal processing to get something out of it. 

Skies were not very good, lot’s of high altitude clouds and contrails. The data has been gathered over maybe 6 or 7 nights for the past weeks.

I have RED and GREEN filtered data still that I did not use in this combination. The total integration time is over 18 hours. I guess lots of rain and clouds should come over to get me reprocessing again? I’m not sure what to think of this image. There’s a fair amount of detail, also the outer regions are visible.

M27 in H-Alpha light

This picture shows the well-know classic object of the Dumbell nebula, or M27. I could image this object for more then 10 hours on several clear nights lately, with 8 hours of H-Alpha narrowband (7nm) and 2 hours of RGB.

Further on M27

Maybe this is not a very good object to practise Ha imaging? I’m not sure what the main consistentency is of this object…. the outer halo does not show very well, and also all blue parts are not visible. I guess this is a work in progress.

Anyhow this is a test object just to get my SGP and automated focusser / filter wheel working. That doesn’t go vbery smooth. I lost a few hours last evening under a clear sky, tampering with the PegasusAstro focuscube, trying to get it working with SGP’s autofocus. In short: it’s not working yet! The picture below is M27 with 178 minutes of H-Alfa.
